As illustrated in FIG. 1, according to an embodiment, a refrigerator includes a body 10 in which a refrigerating compartment 12 and a freezing compartment 11 are provided in an upper portion and a lower portion thereof, respectively, and a pair of doors 20R and 20F rotatably installed on a front surface of the body 10 to open and close the storage compartment 11 and 12 by rotating.

In addition, the refrigerator includes refrigeration cycle components such as a compressor 13, a condenser (not shown), an evaporator 14 (refer to FIG. 2), and an expansion valve (not shown).

The body 10 is formed in a vertically long rectangular housing shape, and the refrigerating compartment 12 is provided at an upper portion and the freezing compartment 11 is provided at a lower portion. As illustrated in FIG. 2, a machine room 15 is provided on the lower rear side of the body 10, wherein a compressor 13 and a condenser (not shown) are disposed in the machine room 15.

In the rear side of the storage compartments 11 and 12, a cooling compartment 17 in which the evaporator 14 is installed, and a duct module 16 configured to divide a space into the storage compartment 11 and 12 and the cooling compartment 17 in the front and rear direction may be disposed. That is, with respect to the duct module 16, a front portion may form the storage compartments 11 and 12, and a rear portion may form the cooling compartment 17.

The duct module 16 may be disposed in both of the freezing compartment 11 and the refrigerating compartment 12, but in this embodiment, a case in which the duct module 16 is installed in the freezing compartment 11 will be described.

The duct module 16 is configured to form a flow path 162 b guiding air in the freezing compartment 11 to the cooling compartment 17 and at the same time, guiding cold air generated in the cooling compartment 17 to the freezing compartment 11, wherein the duct module 16 serves to uniformly distribute the cold air to the freezing compartment 11 as a whole.

As illustrated in FIGS. 3 and 4, the duct module 16 includes a front duct 161, a rear duct 161 coupled to a rear side of the front duct 161 to form the flow path 162 b together with the front duct 161, and a fan assembly 163 configured to circulate air.

The front duct 161 is disposed on the side of the freezing compartment 11, which is located on a front side, and forms a front side end portion of the duct module 16. The front surface of the front duct 161 faces the freezing compartment 11, and a rear surface thereof faces a front surface of the rear duct 162.

The front duct 161 includes a mounting groove 161 a and a guide portion 161 e, wherein the mounting groove 161 a is recessed at an upper portion of the rear surface of the front duct 161 facing the rear duct 162, to allow the fan assembly 163 to be mounted thereon, and the guide portion 161 e is provided in the lower portion of the front duct 161 to guide air, which is suctioned from the freezing compartment 11 to the cooling compartment 17. The guide portion 161 e is extended to be inclined in the upper front side.

In addition, the front duct 161 includes a plurality of cold air outlets 161 b configured to allow cold air to be distributed and supplied to the freezing compartment 11. In this embodiment, a pair of the cold air outlet 161 b is disposed separated in the left and right side at the upper, middle, and lower portions of the front duct 161, respectively.

Therefore, the cold air is distributed and discharged to opposite sides of the upper, opposite sides of the middle and opposite sides of the lower portion of the freezing compartment 11 through the cold air outlet 161 b, and thus the freezing compartment 11 may be uniformly cooled as a whole.

The front duct 161 includes a plurality of locking portions 161 d is formed in a hook shape and configured to be engaged with a locking groove 162 e of the rear duct 162 described later.

The rear duct 162 is disposed on the side of the cooling compartment 17, which is located on the rear side of the rear duct 162, to form the rear side end portion of the duct module 16. The rear surface of the rear duct 161 faces the cooling compartment 17, and the front surface thereof faces the front surface of the front duct 161.

As illustrated in FIG. 5, the rear duct 162 includes a cold air inlet 162 a and a plurality of flow path forming portions 162 c, wherein the cold air inlet 162 a is provided in an upper portion of the rear duct 162 to correspond to the fan assembly 163 so as o allow cold air of the cooling compartment 17 to be suctioned to the inside of the duct module 16, and the flow path forming portion 162 c protrudes from the front surface of the rear duct 162 to form the flow path 162 b.

In this embodiment, the flow path forming portion 162 c includes a pair of flow path forming portions 162 c disposed separated in the left and right side, and a single flow path forming portion formed in approximately inverted V shape between the pair of flow path forming portions to divide the flow path 162 b into two parts.

Accordingly, the flow path 162 b is extended from the upper portion to the lower portion and divided into two parts so that cold air is guided and evenly distributed to two cold air outputs 161 b, which are placed in the middle of the front duct 161, and two cold air outlet 161 b, which are placed in the lower portion of the front duct 161.

The rear duct 162 includes a sealing portion 162 d extended from the front end of the flow path forming portion 162 c placed on the side of the front duct 161, to be parallel with the rear surface of the front duct 161 so as to be in contact with the rear surface of the front duct 161 in the surface contact manner. The sealing portion 162 d prevents the cold air passing through the flow path 162 b, from leaking through a space between the front end of the flow path forming portion 162 c and the rear surface of the front duct 161.

The sealing portion 162 d includes a pair of sealing portions 162 d extended from the pair of the flow path forming portion 162 c to opposite lateral sides, and a single sealing portion 162 d formed inside of the flow path forming portion 162 c that is formed in an approximately inverted V shape. The sealing portions 162 d have a width W1 (refer to FIG. 6) in the left and right direction and the width W1 of the sealing portions 162 d is changed to correspond to the shape of the flow path 162 b.

The rear duct 162 includes the plurality of locking grooves 162 e to which the locking portions 161 d of the front duct 161 are locked. In this embodiment, the locking portions 161 d protrude from four ends such as the upper, lower, left, and right ends of the front duct 161, to the rear side, and the locking grooves 162 e are concave on the rear sides of four ends such as the upper, lower, left, and right of the rear duct 162.

In order that the locking portions 161 d of the front duct 161 is engaged with the locking grooves 162 e of the rear duct 162, the front duct 161 and the rear duct 162 are coupled to each other in the front and rear direction as illustrated in FIGS. 6 and 7 and thus the front surface of the sealing portion 162 d and the rear surface of the front duct 161 are in contact with each other in a surface contact manner, as illustrated in a C part shown in FIG. 9.

Since it is very difficult for cold air to pass between the front surface of the sealing portion 162 d and the rear surface of the front duct 161 which are in contact with each other in the surface contact manner, it may be possible to prevent the leakage of the cold air without a separate sealing member that is interposed between the front duct 161 and the rear duct 162.

In order to more reliably prevent the leakage of the cold air, the front duct 161 includes an auxiliary sealing portion 161 c configured to protrude from the rear surface of the front duct 161 to have a shape corresponding to the flow path forming portion 162 c so as to be in contact with the rear duct 162 in the surface contact manner. In this time, the auxiliary sealing portion 161 c has a certain width W2 (refer to FIG. 6) in the front and rear direction.

As mentioned above, since the auxiliary sealing portion 161 c is formed in a shape corresponding to the inner surface of the flow path forming portion 162 c, when the front duct 161 and the rear duct 162 are coupled to each other as illustrated in FIGS. 7 and 8, the auxiliary sealing portion 161 c is inserted into the flow path 162 b as illustrated in FIG. 8, and thus the auxiliary sealing portion 161 c is in contact with the flow path forming portion 162 c in the surface contact manner, as illustrated in a D part shown in FIG. 9.

It is difficult for the cold air to pass between the auxiliary sealing portion 161 c and the flow path forming portion 162 c, which are in the surface contact state, and thus it may be possible to more reliably prevent the cold air passing the flow path 162 b from leaking therethrough.

Through experiments, it was confirm that when the auxiliary sealing portion 161 c is formed in the front duct 161 as described above, it is required that a sum of the width W1 of the sealing portion 162 d and the width W2 of the auxiliary sealing portion 1161 c is 25 mm or more in order to reliably prevent leakage of cold air from the flow path 162 b.

Since the auxiliary sealing portion 161 c supports the inner surface of the flow path forming portion 162 c as described above, the auxiliary sealing portion 161 c serves to guide the flow path forming portion 162 c to be installed at an accurate position and to prevent deformation of the flow path forming portion 162 c.

As illustrated in FIG. 4, the fan assembly 163 includes a blowing fan 163 a rotating to suck and to discharges air, a drive motor 163 b generating a rotational force to rotate the blowing fan 163 a, and a motor bracket 163 c coupled to the drive motor 163 b and then mounted to the mounting groove 161 a to allow the fan assembly 163 to be fixed to the flow path 162 b of the duct module 16.

In this embodiment, the blowing fan 163 a is implemented by a centrifugal fan that sucks air in the axial direction and discharges the air radially outward, wherein the blowing fan 163 a is disposed at a position corresponding to the above-described cold air inlet 162 a.

In the above embodiment, the duct module 16 is applied to the freezing compartment 11 to distribute and supply the cold air to the freezing compartment 11, but it is merely an example. Alternatively, the duct module 16 may be applied to the refrigerating compartment 12 in the same manner.

In this embodiment, the flow path forming portions 162 c protrude from the front surface of the rear duct 162, and the sealing portion 162 d is formed in parallel to the rear surface of the front duct 161 from the front end of the flow path forming portion 162 c, but is not limited thereto. Alternatively, the flow path forming portions may protrude from the rear surface of the front duct, and the sealing portion may extend from the rear end of the flow path forming portion to be in parallel with the front surface of the rear duct. Further, in this case, it is appropriate that the auxiliary sealing portion protrudes from the front surface of the rear duct to the front side.

In this embodiment, the front duct 161 includes the auxiliary sealing portion 161 c, but the auxiliary sealing portion 161 c is not essential. Therefore, it is possible to exclude the auxiliary sealing portion 161 c. In this case, through experiments, it was confirmed that the width of the sealing portion 162 d is 25 mm or more to prevent the leakage of cold air through between the front surface of the sealing portion 162 d and the rear surface of the front duct 161.

In this embodiment, the auxiliary sealing portion 161 c is formed to correspond to the entire portion of the flow path forming portion 162 c, but is not limited thereto. Alternatively, the auxiliary sealing portion 161 c may be formed to correspond to a part of the flow path forming portion 162 c. That is, since there may be a portion in which the sealing portion 162 d does not have a sufficient width due to the shape of the flow path forming portion 162 c, it may be possible to restrictively form the auxiliary sealing portion 161 c only in such a portion.

As is apparent from the above description, the refrigerator prevents the leakage of the cold air without interposing a separate sealing member, since the flow path forming portions are extended from any one of the rear surface of the front duct and the front surface of the rear duct, and a sealing portion extended from the flow forming portions makes a surface contact with the other one of the rear surface of the front duct and the front surface of the rear duct.

Although a few embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
